In the last entry we just did some basics of the X10 system, now we’ll go over using them efficiently.

So who wouldn’t love to pull up to your house, get out of your car, walk in your house and all the lights and devices you love are already on? Or maybe your just want to save on your electric bill, either way with about 50 bucks you’ll be on your way to home automation paradise. This guide is not exactly intended from someone not at least kinda familiar with linux, and you should have at least used a screwdriver once or twice.
This requires:
- Linux computer (I’m using Ubuntu 7.10, also works with CentOS5)
- WS467 Modules – Their either 7 bucks a piece off eBay or 3 for 15 – Replacement wall switches
- CM11a – About 10 bucks, runs the computer interface for the x10 control, stores macros. Uses a serial port, make sure you got one still!
- Optional – Remotes -
- KR19A - This keychain remote control two devices, On/Off/Dim – Simple & small
- UR73A – This remote will do it all, don’t get up from your lazy boy just to turn off lights!
- Very little experience with wiring.
- 1 Flat-head & 1 Phillips screwdriver
- A volt-meter is a GREAT investment, not necessary, but can eliminate questions and problems very quickly.
